The objective of the present study was to estimate the association between income and mortality in a random sample of Danish citizens. This article investigates the validity of five theories on the association between income and mortality, by testing whether these theories could find support in analyses based on Danish data. From the adult population aged 18-64 of Central and Northern Jutland, a random sample of 102.251 individuals was drawn as of 1 January 2001. For each of these persons, relevant information, such as age, sex, place of living (municipality), family size and gross family income for the calendar year 2000, was extracted from administrative registers. Logistic regression analyses were performed for males and females separately, and a dichotomous variable (death occurring during 2003, yes/no) was used as the dependent variable, while age and various income measures served as explanatory variables. In accordance with the Absolute-Income Hypothesis, the analyses suggest a significant, negative association of the 1-year mortality risk with income. Furthermore, the present analyses lend some support both to the Relative-Position Hypothesis and the Deprivation Hypothesis. Moreover, neither the Relative-Income Hypothesis, nor the Income-Inequality Hypothesis could be supported.
